Zusammenfassung: | To prevent dielectric breakdown in an insulating layer between a back electrode and a metal substrate.SOLUTION: A solar battery module comprises: a conductive substrate with an insulating layer formed on a light-receiving surface side; a photoelectric conversion element that has a first electrode layer formed on the insulating layer, a second electrode layer formed at the light-receiving surface side from the first electrode layer, and a photoelectric conversion layer formed between the first and second electrode layers; and a pair of electrodes that output a power generated at the photoelectric conversion element. One of the pair of electrodes is electrically connected with the first electrode layer and the conductive substrate, and the other electrode is insulated from the conductive substrate.SELECTED DRAWING: Figure 1
【課題】 裏面電極と金属基板の間の絶縁層における絶縁破壊を抑止する。【解決手段】 太陽電池モジュールは、受光面側に絶縁層が形成された導電性基板と、絶縁層の上に形成される第1の電極層と、第1の電極層よりも受光面側に形成される第2の電極層と、第1の電極層と第2の電極層との間に形成される光電変換層とを有する光電変換素子と、光電変換素子で生成される電力を出力する一対の電極と、を備える。一対の電極のうち、一方の電極は第1の電極層および導電性基板と電気的に接続され、他方の電極は導電性基板から絶縁される。【選択図】 図1 |
